Patent GB-804972-A (GB)
Title: Improvements in or relating to photography
IPC: C09B1/20
Filed: 1955-03-09
Abstract: 804,972. Photosensitive element for multicolour diffusion-transfer procedure. INTERNATIONAL POLAROID CORPORATION. March 9, 1955 [March 9, 1954], No. 6905/55. Drawings to Specification. Class 98(2) A multiplicity of silver halide elemental portions containing dye developers and normally exposable at different wavelengths are arranged on a support in side by side relation in colour screen pattern to produce, after exposure and development, non-diffusible images in exposed areas and dye images in a print-receiving material by transfer of dye developer from unexposed areas, to yield colour preferably complementary to the colour of the wavelength range of the silver halide portion from which the dye developer diffuses. A container of processing liquid may be adhered to the surface of the photosensitive element or to the receiving material to enable image production by passage through pressure rolls. In the preferred method, the dye developers are always included in the emulsions and they produce immobile oxidation products in the areas of the silver images, to allow transfer from the non-image areas to the receiving layer without reaction in the latter, immobility resulting from insolubility of the oxidation products or the ability of the dye developers to tan or harden the silver halide carrier material. The dye developers may be indicators requiring the use of a volatile alkali in the developer or the presence of acid in the receiving layer to produce the desired colours. They may be utilized to control the transfer of other materials such as dyes or couplers or dye couplers. Dye developers quoted are 2-naphthylazohydroquinone and phenylazohydroquinone for yellow, 2-hydroxynaphthylazohydroquinone and 1-amino-2-naphthol-4-azobenzene for magenta and 1, 4-bis-(2<SP>1</SP>, 5<SP>1</SP>-dihydroxyanilino) - anthraquinone for cyan, and for other dye developers reference is made to Specifications 804,973, 803,974 and 804,975 [all in Group IV(c)]. Specifications 684,591, 684,592, 685,685, 706,921, 804,971 and 804,976 also are referred to.

Fig. 5 shows tumblers P, Q, R, S, each with an integral part p, q, r, s, providing a second operating edge. The tumblers are operated directly by the bits of a servant-key F<2> and indirectly by the bits of a master-key F<1> acting on the parts p, q, r, s. By having tumblers with edges of different depth, 'but each with a second edge of the same depth, a number of locks with individual keys but all operable by one master-key may be made.
Patent GB-645037-A (GB)
Title: Purification and isolation of penicillin
IPC: C07D499/18
Filed: 1948-03-08
Abstract: Penicillin is extracted from a substantially neutral aqueous solution, i.e. a solution of pH 4.0-8.0, such as the culture medium, by extraction with an organic solvent in the presence of a tertiary amine.  The aqueous solution of penicillin may optionally contain inorganic salts.  Where the penicillin consists of a number of chemically distinct compounds, such as 2-pentenyl-, benzyl-, n-heptyl- or p-hydroxy benzyl-penicillin, the process may result in a partial separation of these components which may be made nearly complete by repetition, e.g. by transferring the tertiary amine salt of penicillin back to aqueous solution as its alkali or alkaline earth metal salt by extracting with aqueous alkali or as its tertiary amine salt by extraction with water or a tertiary amine and subjecting the aqueous solution of penicillin obtained to extraction as described above.  Suitable tertiary amines are N-ethyl hexamethylene imine, N-ethyl piperidine, trimethylamine, benzyldimethylamine, N - ethylmorpholine and N - benzyl hexamethylene imine.  Suitable organic solvents include amyl acetate, chloroform, tetrachloroethane and ethyl acetate. The extractions may conveniently be carried out by countercurrent methods, e.g. in a partition chromatograph column such as by passing an organic solvent solution of a tertiary amine salt of penicillin down a column of silica gel impregnated with water and extracting the column with an organic solvent solution of a tertiary amine.  Many examples of extraction processes according to the invention are given.  Reference has been directed by the Comptroller to Specification 642,369.

Title: Pallet Loading Machine.
Inventor: GOVAN DAVID EDWARD FREDERICK
IPC: B65G57/00
Filed: 1967-02-15
Abstract: 1,150,300. Pallet loading machine. E.C.C. QUARRIES Ltd. 15 Feb., 1968 [15 Feb., 1967], No. 7202/67. Heading B8C. A pallet loading machine raises a stack of pallets in steps, the top one being loaded by conveyer means and pushed via a transfer passage on to the top of a stack of loaded pallets which are lowered in identical steps to the steps in which the pallets are raised. The articles are of no greater height than the pallet runners and capable of fitting between them so that loaded and unloaded stacks are of equal height. A stack 6 of pallets 12 on a stillage 13 is delivered via conveyers (9 and 7, Fig. 1, not shown) to a supply compartment 2. The stack and stillage are then pushed by a framework 18 on to a horizontally movable conveyer 19 within the pallet loading compartment. Here prongs 25 of a fork-lift arrangement 27 raise the stack in steps leaving the stillage on the conveyer. The stack is lifted one step equivalent to the height of a pallet, and the top pallet of the stack loaded with an article e.g. a cementitious slab, transported from a machine making it, by a carriage from which depends a suction head 35, see also Fig. 3 (not shown). The suction head can be spring-loaded so that on releasing the articles the head lifts for clearance purposes. The loaded pallet is then pushed via ram 14, on to a transfer platform 33, in turn pushing one already in this position on to the top of the loaded pallets stacked on prongs 26, of a forklift arrangement 28. The latter is coupled to the fork-lift 27 via chain 30 so for any step up by 27, 28 is similarly lowered. The stack is thus formed and lowered on to the stillage 13 prepositioned by the conveyer 19. In an alternative arrangement (not shown) the stillage and conveyer 19 are not used, thereby increasing the stack capacity.

Patent GB-1603982-A (GB)
Title: Fluid controller
IPC: G05D7/01
Filed: 1978-02-23
Abstract: The constant fluid-flow controller has a tube (101) in which there is mounted a member (104) which is slotted with grooves (105) and is operationally connected to an elastic ring (122). This ring (122) bears against the slotted member (104) under the influence of the fluid pressure. Located between the grooves are webs (120) which each have a recess (126) directed transverse to the flow direction. The elastic ring (122) is constructed as a hose-like section whose length is greater than the length of the recesses. The constant fluid-flow controller is intended to keep constant the rate of flow of a fluid medium in a tube independently of changes in pressure. It is preferably used in continuous-flow heaters which are heated electrically or by fuel and in which changes in pressure of the water to be heated would entail undesired changes in temperature. <IMAGE>

Abstract: 1419451 Feeding and delivering sheets A B DICK CO 15 Feb 1973 [16 Feb 1972] 7563/73 Heading B8R [Also in Division G2] A copying apparatus wherein original documents 22 are fed from a tray 20 to an exposure location 44 and copy sheets 18 are fed from a tray 16 for a copying location 92 comprises trailing edge detectors 154 and 190 for the original and copy sheets respectively the detectors being coupled to a circuit such that sensing of the trailing edge of an original initates feed of the next original whereas sensing of the trailing edge of a copy sheet initiates feed of a further copy sheet only after trailing edges of both the original and the copy sheet have been sensed. As shown the original is fed by a friction separator roller 24 operating against a fixed roller 26 and is advanced until its leading edge engages stop 36. The sensing of the leadedge by detector 154 disables roller 24 and energizes copy sheet separator roller 76. A separated copy sheet operates leading edge detector 170 which causes removal of stop 36 and lowering of drive roller 32 (and also supplies power for exposing light source 110 and for charging station 86). When the trailing edge of the original passes detector 154 separator roller 24 is activated to commence feed of the next original to the ready position against stop 36 which is again raised into the operative position whilst drive roller 32 is moved to its inoperative position. When the trailing edge of a copy sheet passes detector 190 the copy sheet separator roller 76 is energized (provided detector 154 has registered the passing of the trailing edge of the original). When the supply of originals is exhausted detector 154 is not actuated and a buzzer is sounded. The buzzer also operates upon exhaustion of copy sheets as determined by the non-actuation of detector 170. Sheet ordering.-The originals are stacked in the same order as they appeared in tray 20 by providing a turning section consisting of cooperating rollers 53, 54 and 56. Thus a multipage document arranged face downwards on the tray 20 is stacked face upwards on tray 62. The end rollers 53 of the turning section are flanged, Fig. la, to engage the edges of the documents and thereby impart rigidily thereto.
